Abstract: The invention contemplates a binocular-telescope construction wherein no precision optical alignment or realignment procedures are needed within the telescope tubes, once the telescope tubes are assembled to their connecting bridge structure. The nature of the connecting bridge structure is such as to provide a range of universal action in the connection of each telescope tube to the bridge structure so that optical-axis parallelism can be mechanically effected and clamped at the universal connections without operating upon any of the individual optical elements within the telescope tube. The universal action and clamping is without prejudice to the single-articulated or double-articulated nature and action of the connecting bridge, for interpupilary-distance accommodation.

Abstract: A non-return valve unit for a bottle having a mechanism for preventing dripping and for giving a controlled discharge of liquid from the bottle, suitable for use with any type of bottle neck by insertion in the said neck and especially for bottles adapted to receive "pilfer-proof" caps. The valve unit consists of only three elements made up generally of a cylindrical slightly frusto-conical body having a brim for preventing dripping and having a septum in its interior where the seat of a generally circular valve is positioned. Radial septa which support an annular guide for the stem of a check or retention valve, form a component part of this septum. An upper chamber in the body houses a pouring device of a frusto-conical shape. The pouring device has a cylindrical wall internally supported by radial septa which ends in a frusto-conical surface; and provides together with the inner cylindrical surface of the pourer a circular area of discharge.

Abstract: A continuous bag sealing machine for heat sealable bags is provided. The machine includes a conveyor belt upon which the bag to be sealed is moved. The upper portion of the bag is gripped by a double pair of "V" belts and is moved through the machine to a hot air nozzle which fuses and seals the top of the bag. As the bag is heated, it is simultaneously stretched to more securely fuse the bag together. A cool air nozzle hardens the seal and a cutting device cuts off the top of the bag. One pair of "V" belts transport the cut-off scrap of the bag out of the device.

Abstract: The subject of the present invention is a transfer device for analysis equipment, which transfer device comprises a track consisting of, inter alia, guide and support rails on which to transfer a pit plate on a transport cassette along the track. The transport cassette includes a traction rail parallel to the guide and support rails. Traction units are fitted onto the track in the transfer device as means operative jointly with said traction rail to move the transport cassette. In order to control the operation of the traction units, the traction rail is provided with sign codes readable by means of an optical reading device. This indicates the position of the cassette relative to the optical reading device so that the transport cassette may be stopped to position the desired line of pits, transverse to the track for operations to be performed in the analysis equipment, such as liquid dosage, photometric measurement operations, etc.

The mounting in a preferred form comprises a single stiffly compliant sheet which is folded at one end, so that an upper panel can be detachably secured in register with a lower panel, there being coacting formations of the registering panels whereby the lens can be supported by and between the panels and via the haptic structure of the lens assembly.

Abstract: The invention contemplates a particular body construction and assembly for a check valve or the like whereby the entire valve assembly may be readily installed as a unit within the bore of standard pipe or conduit, or a standard fitting therefor. A single circumferentially extending radially inwardly open groove in the bore of the pipe, conduit or fitting, faces a corresponding radially outwardly open groove in the valve body, and stiffly compliant circumferentially extensive retainer element such as a wire of suitable gage substantially fills these grooves to retain the inserted valve in place. The retainer element is adapted for ready removability, to enable servicing or removal of the inserted valve, and the valve body is so externally characterized as to unambiguously assure valve installation in the correct direction of desired flow.
